IMPROVEMENT IN PLOWS.

Specification forming part of Letters Patent N 0. 191,469, dated May 29,1877; application filed April 26, 1877.

To all whom it may concern.-

Be it known that I, FRIEDRICH RICK, of Detroit, in the county of Wayneand State of Michigan, have invented certain new and useful Improvementsin Plows and I do hereby declare the following to be a full, clear, andexact description of the invention, such as will enable others skilledin the art to which it pertains to make and use it, reference being hadto the accompanying drawings, which form part of this specification.

My invention relates to an improvement in plows; and it consists in thearrangement and combination of devices that will be more fully describedhereinafter, whereby the colter can be adjusted back and forth, as maybe required.

The accompanying drawings represent my invention.

V 00 represents the beam, that is made of aflat bar of iron, stamped orotherwise shaped into the desired form, and which is bolted in asuitable recess in the side of the standard, and has its rear endfastened to the side of one of the handles 0. Pivoted to the beam, nearits front end, is the clevis d, which has a hole, e, made through it, sothat a bolt can be passed down through it and the extreme front end ofthe beam, through which is made a series of holes, 9, arranged in thearc of a circle.

By means of this arrangement the clevis can be adjusted horizontallyback and forth, so as to make the plow take more or lessland, as may bedesired.

Instead of the colter It being rigidly secured to the standard I or tothe land-side i, it has its rear end made to extend far backward, isslotted along its side for nearly its entire length, and has its rearend bent inward at right angles to its length. Passinginward through theslot and the standard is the headed clamping-bolt 0, which serves as aguide to keep the colter straight, and can be made to also clamp itrigidly in position after it has once been adjusted.

Swiveled on the inner side of the lower end of the handle 0 is anadjusting screw, it, which passes through the rear end of the colter,and has its front end steadied in therear side of the standard. Byapplying a wrench or other suitable tool to the rear end of this screw,so as to turn it, the colter can be moved back and forth at will,andasit wears away from constant use, it can be moved forward from time totime without the expense or trouble of applying a new one.

If desired, the beam, standard, and handles may be made of wood.

Having thus described my invention, I claim- In combination with theslotted colter, the screw it, that is swiveled to the side of thehandle, and made to move the colter back and forth, substantially asdescribed.

In testimony that I claim the foregoing I have hereunto set my hand this16th day of April, 1877.
